Ten Nights of Killing and Mayhem

A tongue-in-cheek horror turn-based strategy/RPG game where you lead a party of students against an army of demonic teachers of a local high school and prevent her from enacting plans for world domination. Each of the 50+ twisted enemies have a unique set of horrific powers and abilities you must overcome in a random order, meaning each campaign presents its own set of challenges with lots of re-playability. Upgrade basic weapons to refined military-grade weaponry, including chainsaws, grenades, rockets, and a tactical nuke.

This game was adapted for the web from earlier versions that used to be DOS- and Windows-based, which were in turn adapted from a physical board game https://virtua-sinner.itch.io/ and I once made as teenagers with too much time on our hands.
